Perseid meteor shower 2021 peaks this week: How to watch the sparkling show

The Perseids will peak on Aug. 11 in the US, but you can catch them blazing across the sky right now. Here’s how.

The Perseid meteor shower, a stunning celestial display, delivers eye-opening shooting stars that can be seen blazing over Earth. We can thank debris from comet 109P/Swift-Tuttle for the spectacle. You don’t want to miss the shower, and here’s how you can see it as it ramps up.

According to NASA, the annual Perseids are active from now through Aug. 24. The space agency says it’s «considered the best meteor shower of the year.» Meteor activity will peak on the night of Aug. 11 and morning of Aug. 12, though NASA also calls out the night of Aug. 12 and morning of Aug. 13 as another great skywatching opportunity.

«The meteors are best viewed from the northern hemisphere, and in ideal conditions with no clouds observers could see up to 50 an hour,» the Royal Astronomical Society said in a statement about the peak, which will be on the night of Aug. 12 for the UK and Europe. The moon will be staying low-key, giving watchers a nice dark sky to work with.

The Perseids are popular for their reliability and the potential for spectacular fireballs. «The Perseids are one of the most plentiful showers (50 to 100 meteors seen per hour) and occur with warm summer nighttime weather, allowing sky watchers to easily view them,» said NASA in a Perseids explainer geared for the Northern Hemisphere.

On July 26, NASA’s Marshall Space Flight Center shared an image of a streaking Perseid meteor spotted by a camera at the Mount Lemmon Observatory in Arizona.

Fireballs can happen when larger pieces of comet debris strike the atmosphere, creating long, bright streaks, the kind that make you say «Whoa!» Ready to get excited? Check out these photos from last year’s shower:

Catch a shooting star

At its simplest, viewing the meteor shower is just about heading out at night and looking up, but there are some steps you can take to improve your chances at catching a good show. You’re in luck if you’re a super-early riser. The pre-dawn hours are a prime viewing time, but NASA also says you can see the meteors as early as 10 p.m. local time.

Some of the biggest obstacles to good meteor viewing are cloudy weather and light pollution. Aim for a clear night and try to get away from city lights. A hammock, blanket or a chair that leans back will save you from craning your neck. Give your eyes plenty of time to adjust to the darkness.

You can spot the meteors anywhere in the sky, though they get their name because they appear to be radiating from the constellation Perseus. To find Perseus, check out a stargazing app that will help you locate the constellation. Perseus isn’t the actual source of the shower, but it can be helpful in tracking down the sometimes elusive streaks of light.

Watch a livestream

The Virtual Telescope Project will host a livestreamed Perseids viewing session on Aug. 10 at 5 p.m. PT. «This year, the sky conditions will be perfect, with no moon interference,» said VTP founder Gianluca Masi in an announcement.

NASA will offer a livestream hosted by the Meteoroid Environment Office at the Marshall Space Flight Center. The streams kicks off at 8 p.m. PT on Aug. 11 on Facebook, Twitter and Youtube.

You don’t have to wait for the mid-August peak to enjoy the action. A dark spot on a clear night can deliver a worthwhile viewing experience throughout the Perseids’ visit. Catch those shooting stars while you can.

Google Is Bringing Gemini AI to Its Smart Home Lineup, Starting Oct. 1

Goodbye, Google Assistant. Hello, Gemini.

It increasingly feels like Google’s AI assistant is omnipresent across our devices and, starting next month, it could also be in your home.

In a post on X on Tuesday, the company teased, «Gemini is coming to Google Home,» and told us to, «Come back October 1.»

At its Made by Google event in August, the company announced Gemini for Home among a slew of other product announcements, so this has been in the works for a while.

Tuesday’s X post teaser appears to show an image of a Nest camera, which Google last upgraded four years ago, suggesting the security camera could be set for a refresh. An upgraded Nest speaker and doorbell, both with 2K camera support, could also be part of the Oct. 1 unveiling.

Google did not immediately respond to CNET’s request for comment.

Android Faithful podcast co-host (and former CNET staffer) Jason Howell is «optimistic» about Gemini replacing Assistant in Google’s smart home products.

«In recent years, I have witnessed my Google Home devices degrading in quality and becoming far less useful for even simple tasks and questions,» Howell tells CNET. «They’ve become buggy and unreliable to the point where I’ve stopped interacting with them for most things.»

Gemini catches dog red-handed

At the Mobile World Congress tech show in Barcelona earlier this year, Howell was impressed by Gemini’s performance with a smart home camera. 

«A smart home camera detected a dog that came into the kitchen to steal a cookie off the counter,» Howell recalls. «Through voice interaction, the homeowner could ask the system what happened to the cookie, and, given the video context from the camera and an understanding of what it saw, the system could tell the homeowner that the dog was the culprit.

«This sort of example empowers users to spend less time looking for answers in lieu of simple voice queries that serve them the answer they are looking for with less effort and less time spent.»

Google announced last month that Gemini for Home will eventually replace Google Assistant in its smart home devices. You’ll still activate Gemini with, «Hey Google,» but the advanced AI tech will be able to better interpret more complex and nuanced instructions and questions.

Maybe you’re stumped as to what to make for dinner, so it could be: «Hey Google, what quick pasta dish can I cook in less than an hour?» or, «Give me a recipe for Caesar salad.» Gemini is also designed to work with thermostats and smart lights, so you might tell it to «turn the temp to 68 degrees» and «turn off all the lights except in the kitchen.»

The market for smart home technology is expected to grow by 23% over the next five years, according to Grand View Research.

Polar Introduces Loop, a $200 Screenless Wearable

Polar’s first fitness tracker with no screen tracks activity, sleep and overall health, the company says.

Fitness tracking company Polar has launched Loop, a $200 screenless wearable that it says will have no subscription fees. Preorders opened on Sept. 3, and the Polar Loop will start shipping on Sept. 10.

Like other fitness trackers, the Polar Loop will log steps, sleep patterns and daily activity patterns but Polar is touting the lack of a screen as «unobtrusive» and «discreet.» The Loop, which is a wearable band for your wrist, has eight days of battery life with continuous use and stores four weeks’ worth of data. It syncs with the Polar Flow app to view stats and analyze sleep and training data, among other information.

Because it has no buttons, activities can be started in the app or passively with what the company calls «automatic training detection.»

It’s available in the colors Greige Sand, Night Black and Brown Copper. Additional band colors are offered for $20 each.

There’s already a market of no-screen wearables, including the Whoop 5.0 wristband and smart rings such as the Oura Ring 3.

Will the Loop measure up?

Whether the Polar Loop’s attempt at simplifying a fitness wearable works out will largely depend on how well it runs and what it offers compared to other devices.

«The company is clearly tapping into the growing demand for screen-free wearables,» says CNET’s lead writer for wearables, Vanessa Hand Orellana. «It feels like a direct answer to the athlete-favorite Whoop band and even the Oura Ring, both of which collect similar health metrics to display and analyze in their respective apps.»

Hand Orellana says Polar has a good reputation, with its signature heart-rate chest straps, and may win over fans by eschewing the subscription fee that the Oura and Whoop require. 

«That said, as with most devices in this space, the real differentiator often comes down to execution… specifically, how well the data translates into clear, actionable insights. Personally, I’m curious to see how the Loop integrates with Polar’s app, which, at least in my experience with their HR straps, hasn’t always been the most intuitive to navigate,» she said.
